"O Jesu Christ, meins Lebens Licht" has been characterized as something between a cantata and a motet. This work is a motet version of the
chorale Ach Gott, wie manches Herzeleid. The lower voices of the choir sing counterpoint to the chorale melody line in the soprano. The accompaniment includes an ascending string motive.
Scoring and structure The piece is scored for
four-part choir. It is structured as a chorus, ''O Jesu Christ, mein's Lebens Licht'', comprising chorale strophes separated by repeated instrumental interludes. The number of strophes sung would likely correspond to the length of the procession for which the work was used. There are two versions of the instrumental scoring: • The first version is unique among the Bach cantatas in not including strings,
cornett, three trombones, and organ; • The second version is for two litui, strings, organ continuo, and optionally three oboes and bassoon. == Publication ==
